Problem adding new domain

Problem adding new domain

Hello: I´m trying to add a domain. When I submit my domain name Zoho pops an sign saying: " the domain name allready exist.". I´m not sure, but a few months ago I added a domain and I erased later. Now, I have not any domain in my domain list and I have this problem trying to add a new one.

Thank you, I love Zoho!!!
